Error: Cannot read property 'getOptional' of undefined(…) about core

Hello,
this has nothing to do with ng2-translate, see: angular/angular#5614

[guillaumeleone]

Same problem.

I don't understand, because in this post angular/angular#5755, it say there is a problem with es6-shim lib.

But in your showcase project, you use this lib.

[ocombe]

Maybe it's a question of version of the libs?
If you can make a project with the problem I'll check it out.

[guillaumeleone]

Oh thank you. Here an example with this problem: https://github.com/guillaumeleone/ng2-cli-translate
It happened when I added TRANSLATE_PROVIDERS in bootstrap file.
(The template was generated with angular-cli)

I have the same issue,

import {HTTP_PROVIDERS} from 'angular2/http';
import {TRANSLATE_PROVIDERS} from 'ng2-translate/ng2-translate';
import {bootstrap} from 'angular2/platform/browser';
import {Application} from './app';
import {ReviverService} from "../service/reviver";

bootstrap(Application, [HTTP_PROVIDERS, TRANSLATE_PROVIDERS, ReviverService]);

ng2_translate_1.TRANSLATE_PROVIDERS is undefined.

@qsahmed check the version of ng2-translate that you use :) the last one is 1.11.0

[qsahmed]

Thanks for the quick reply.
I am using 1.11.0
"karma-phantomjs-launcher": "^0.1.2", "ng2-translate": "^1.11.0", "phantomjs": "^1.9.8",

This error message is a consequence, original error is that injector could not resolve dependency. Almost impossible to trace unresolved component without putting console.logs into framework code (_constructDependencies).
